Abstract

A surface-textured polishing pad suitable for chemical-mechanical polishing comprises a porous polymeric foam having an average pore cell size in the range of 60 μm or less. At least 75% of the pores in the foam have a pore cell size within 30 μm of the average pore cell size. The pad has at least one textured surface that includes divots having a depth in the range of 25 μm to 1150 μm, a width in the range of 0.25 μm to 380 μm, and a length-to-width aspect ratio of 1 to 1000. In addition, the at least one textured surface of the pad includes at least 10 divots per square centimeter of surface area, and has an average surface roughness of at least 5 μm. Preferably, at least one textured surface has at least one pattern of spaced, parallel grooves imprinted thereon.
